1.2363 Steel for through hardening

Designation

Chemical composition:

Strength:

max. 240 HB
(≈ max. 820 N/mm²)

Thermal conductivity at 100 °C:

19 W/m K

Character:

steel for through hardening with good machinability, high wear resistance and low warpage; very good dimensional stability, toughness and through hardenability

Application:

mould plates and inserts as well as cutting punches, wear plates and cutting plates with high requirements on toughness

Treatment by

is possible:
Polishing, etching, nitriding, hard chroming

Heat treatment:

Soft annealing:
800 to 840°C for about 4 to 5 hours slow controlled cooling of 10 to 20°C per hour to about 650°C further cooling in air, max. 230 HB

Hardening:
950°C to 980°C
quenching in calm air
obtainable hardness: 62 HRC

Tempering:
slow heating to tempering temperature immediately after hardening; tempering twice is recommended; rapid cooling following the tempering improves the dimensional stability;

maximum hardness achievable after tempering: 58−60 HRC
